As the accelerator system validation activity to demonstrate deuteron acceleration by the low-energy section of an IFMIF deuteron accelerator up to 9 MeV with a beam current of 125 mA in CW, a linear IFMIF prototype accelerator (LIPAc) was commissioned under the Broader Approach (BA) Agreement of the fusion program between Japan and the EU. A SRF linac containing eight half-wave resonators (HWRs) operating at 175 MHz and eight focusing solenoids to accelerate the energy from 5 MeV to 9 MeV and the licensing required by the High-Pressure Gas Safety Law (HPGSL) in Japan are reported.}, pages = {283--290}, title = {核融合中性子源用大電流超伝導加速空洞の開発と高圧ガス許認可}, volume = {54}, year = {2019} }
